Application filed June 22, 1918. Serial No. 241,394.

To all whom it may concern:

Be it known that I, CLAnENon E. MYERS, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Door-Blocks forSilos, of which the following is a specification. i

This invention relates to silo door block construction and is designedparticularly as an improvement for use in the type of door blocks usedin building cement stave or block silos. In this construction, it iscustomary to form a block of sulfioient size and provide the same with asuitable opening to operate as a door opening and mount these blockssuccessively in position as the silo is built up. It is my aim toimprove and strengthen these blocks to such an extent that they will notreadily be broken and at the same time facilitate the ready attachmentof the silo hoops or circumferential tie rods. My invention therefore,broadly stated,'takes the form of a reinforcement embedded in thematerial of the door block and anchor clips secured to thisreinforcement but 'proj ecting outwardly therefrom in such form andarrangement as will facilitate the ready attachment of the silo hoops ortie rods.

The preferred embodiment of my invention is shown in the accompanyingsheet of drawings wherein similar characters of reference designatecorresponding parts and wherein,

Figure l is a View in side elevation of a door block shown in positionand constructed in accordance with my invention,

Fig. 2 is a horizontal section taken on line 2-2 of Fig. 1 and Fig. 3 isa similar horizontal section showing the endless reinforcement withanchor clips attached separately.

In Figs. 1 and 2, the silo is designated by the reference numeral 1 andis shown as being built from cement blocks although it will beunderstood that my invention is not limited to the use of this type ofconstruction. The door openings for a silo to which my invention isapplicable are formed by means of a plurality of blocks 2 provided witha central door opening 3 and formed of such size as to be readilyadapted to the size of the material from which the silo is Specificationof Letters-Patent.

built. These blocks are usually formed of cement and built upon theground as the silo 1s being erected. It is my intention that areinforcement member such as the angle shown at 4 will be placed in themold as the block is being formed so that this reinforcement is embeddedin the block itself. The angle member is shown as being shaped toendless form and its ends united as shown at 5. The opposite sides ofthis angle reinforcement are provided with anchoring clips such as shownat 6 which clips are designed to receive the ends of the silo hoops 7.The clips themselves are secured in holding relation with thereinforcement so thatboth may be readily set in position in the mold.The clips themselves are somewhat U-shaped, the legs 8 being secured tothe angle by means of the rivets shown at 9 and the opposite legs 10being bent down a distance to engage the silo body after the mannershown in Fig. 2. Both legs are provided with openings through which thetie rods may pass and then be held in adjusted position by means of thenuts 11.

From the foregoing description, taken in connection with theaccompanying sheet of drawings, it will be apparent that I have provideda structure whereby the door slab may be guarded against breakage and atthe same time I combine with this a means for readily securing the tierods in adjusted position.

What I claim is:

1. In a silo, a door frame provided in said silo and formed from acementitious material, a. metallic reinforcement embedded in andconforming substantially to the contour of said frame, a tie rodarranged to circumferentially embrace said silo and having its endsspaced apart, and a plurality of angle clips rigidly secured to saidreinforcement and projecting outwardly therefrom for attachment with theends of said rod.

2. In a silo, a concrete door frame positioned in said silo, a metallicreinforcement embedded in said frame, anchor clips rigidly secured tosaid reinforcement and projecting exteriorly of said frame, said clipshaving their outer ends angularly bent to engage with the silo body, anda tie rod formed to circumferentially embrace said silo and having theends thereof secured to the outer angular ends of said anchor clips.

bedded in the material of said block, and a I In testimony whereof Iafii pan-"of U-shaped anchor clips for the silo in presence of tWoWitnesses.

3; In a door block for a silo, an angle being provided with means forattaching the 10 member shaped to endless form and .emsilo hoops.
